Advanced Optimization of Source Power Delivery for Transmission Loss Reduction—Case Study

The article presents the development and laboratory validation of a current optimization algorithm designed for voltage-source systems. The algorithm was implemented in a real laboratory setup using a synchronous generator driven by a DC motor to model a fragment of a power system. During tests, transient states were intentionally inducted to evaluate the algorithm’s performance. The proposed optimization method effectively reduced instantaneous current peaks by over 60% and the overall RMS current by approximately 4%, leading to lower power losses and decreased conductor temperatures. These improvements resulted in nearly 8% minimization of power losses and a noticeable reduction in heat generation during transient and fault conditions. The solution is particularly suitable for islanded networks with renewable and unstable energy sources.
